Migrate Export Fails (R77.30 OpenServer)

In my test environment I wanted to test migrate tools, but I failed to execute migrate export on my primary Management server. I had no issues with to execute the migrate export on standby management server.

I looks like your partitions are too small which is why there is so little space left on them. Try to recreate your lab with a bigger harddrive as /var/tmp is hosted on your root partition while /var/log is a dedicated log partition.

I am still not able to get output of migrate export. In log file the errors and warnings are still the same.It is interesting as from standby mgmt node, where I had same amount of HDD space and same size of partitions as on primary (before change of the lv_current) I am able to run the migrate export. Databases are synchronized, so If I understood correctly all the data from DBs should be on standby mgmt. server as well. Anyway it is very simple setup (few objects and like 10 rules) just for my testing.

Based on your logfile, the migrate export appears to be barfing while handling the Endpoint Policy Management (uepm) piece of your config. Are you actually using Endpoint Policy Management on this SMS? Try the following:

1) If not using Endpoint Policy Management, uncheck it on your SMS object in the SmartDashboard. Perform an "Install Database" operation and try the migrate again.
